------------------------------------------
> xsd:base64binary parser behavior change
> ---------------------------------------
>
> Key: XERCESJ-1728
> URL: https://issues.apache.org/jira/browse/XERCESJ-1728
> Project: Xerces2-J
> Issue Type: Bug
> Affects Versions: 2.11.0, 2.12.0, 2.12.1
> Reporter: David Ritter
> Priority: Minor
>
> I've recently upgraded my project from Xerces-J 2.7.0 to Xerces-J 2.12.1 and
> I'm seeing a change in base64binary enumeration parsing behaviour
> Given this schema
> {code:xml}
> <?xml version='1.0'?>
> <xsd:schema xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
> <!-- Schema to test facets for the xsd:base64Binary datatype. -->
> <xsd:element name="facetTest" type="FacetTestComplexType"/>
> <xsd:complexType name="FacetTestComplexType">
> <xsd:sequence>
> <xsd:element name='enumeration' type='EnumerationType' minOccurs="0"/>
> </xsd:sequence>
> </xsd:complexType>
> <!-- ***** Enumeration ***** -->
> <xsd:simpleType name='EnumerationType'>
> <xsd:restriction base='xsd:base64Binary'>
> <xsd:enumeration value='Ab1+'/>
> <xsd:enumeration value='7 d Ec'/>
> </xsd:restriction>
> </xsd:simpleType>
> </xsd:schema>
> {code}
> Our code calls {{xsSimpleType.getLexicalEnumeration()}} and iterates over the
> list of enumeration values. Prior to Xerces-J 2.11.0, {{<xsd:enumeration
> value='7 d Ec'/>}} would be returned as {{7dEc}}. From Xerces-J 2.11.0 on it
> now returns {{7 d Ec}}.
> This now causes a validation issue however as an instance value of {{7dEc}}
> which used to be viewed as legal is now illegal.
> Is this a bug or expected change in behaviour and my application needs to be
> updated?
